Strength vs. endurance training

[Maawen]

Hello.

Today I read two different articles on some scientific findings from 2010 and 2012, which showed that if you trained until fatigue, then the muscles would get the same amount of fiber growth whether you did a 80% or 30% RM. It was the fatigue that mattered. So my question is, why runners don't seem to get muscle growth when running until fatigue? Or lies the answer in, that a runner doesn't have every stride/step counting as a 30% RM but more like a 0.01% or something like that, because a runner makes something like 1,000 repetitions instead for about 20-30 per session?

I hope it makes sense.

Sprinters get muscular development, probably because they train short duration. Longer distance runners don't. The duration seems to be unimportant within a reasonable range, and that range may be up to 2 minutes or so. After that you start using different energy systems. Ideal is likely to use a blend of intensities, some low reps, some higher so you target both the ATP-CP and the Anaerobic system. Training the Aerobic system doesn't provide any hypertrophy or strength adaptation but your endurance improves.

Endurance fibers hypertrophy at about 50 percent of fast twitched fibers.

That mean muscle tension (force) also contribute to hypertrophy.

Endurance Training Is Catabolic

...studies have shown a rise in testosterone levels and GH (both during and after the exercise) during short-term high volume, high strength level exercises (such as weight lifting, sprinting, etc.), while with strenuous prolonged exercises (such as marathon running and other endurance events, or with overtraining in high strength level exercise), the testosterone and GH level are depressed while the cortisol levels are elevated.
